What should you do if a patient has increased intracranial pressure?

How is increased ICP treated?

1. Taking medicine to reduce swelling.
2. Draining extra cerebrospinal fluid or blood around the brain.
3. Removing part of the skull (craniotomy) to ease swelling (though this is rare)

What are the key treatment options to manage increased ICP?

Medical management of increased ICP should include sedation, drainage of CSF, and osmotherapy with either mannitol or hypertonic saline. For intracranial hypertension refractory to initial medical management, barbiturate coma, hypothermia, or decompressive craniectomy should be considered.

How does hypertonic saline work for ICP?

Hypertonic saline and mannitol are effective because they do not cross the blood-brain barrier (much), and thereby draw cerebrospinal fluid out of the cranium and fluid out of the injured brain, reducing pressure and further injury.

How does mannitol work for ICP?

Mannitol lowers ICP through two distinct effects in the brain. The first, rheological effect, reduces blood viscosity, and promotes plasma expansion and cerebral oxygen delivery. In response, cerebral vasoconstriction occurs due to autoregulation, and cerebral blood volume is decreased.

What are the four stages of increased intracranial pressure?

Intracranial hypertension is classified in four forms based on the etiopathogenesis: parenchymatous intracranial hypertension with an intrinsic cerebral cause, vascular intracranial hypertension, which has its etiology in disorders of the cerebral blood circulation, meningeal intracranial hypertension and idiopathic …

What happens to vital signs with increased intracranial pressure?

When this happens, the patient will exhibit Cushing’s triad: a rise in systolic blood pressure with a decrease in diastolic pressure (widening pulse pressure), bradycardia (heart rate less than 60 beats/minute), and bradypnea (slow respirations). A patient with these signs requires immediate intervention.

How can you prevent increased intracranial pressure?

If a patient is suspected of having an increased ICP, methods to reduce the pressure from increasing further include elevating the patient’s head to 30 degrees, keeping their neck in a neutral position, avoiding overhydration, maintaining normal body temperature and maintaining normal oxygen and carbon dioxide levels ( …

Which drug treatment helps reduce ICP by expanding plasma and the osmotic effect to move fluid?

Osmotherapy. Mannitol is a mainstay in the control of elevated ICP. An osmotic diuretic, mannitol was commonly thought to reduce ICP by reducing intracranial water, but, as first shown by Barry and others, is now recognized to also expand plasma volume and decrease viscosity.

What is intracranial pressure?

Intracranial pressure (ICP) is defined as the pressure within the craniospinal compartment, a closed system that comprises a fixed volume of neural tissue, blood, and cerebrospinal fluid (CSF).

Why would you give a patient a hypertonic solution?

Hypertonic solutions are also useful to patients with fluid overload when they need electrolytes. This includes conditions such as Heart Failure or severe edema. 3\% Saline can provide patients with needed electrolytes, all while adding minimal water.

What is the action of mannitol?

Mannitol may be used to reduce intraocular pressure when given intravenously. The mannitol is a new solute in the intravascular space, which increases the tonicity of the blood plasma. The increased tonicity of the blood plasma draws water out of the vitreous humor of the eye and into the intravascular space.

When should I go to the ER with IIH?

NEW YORK (Reuters Health) – People who experience severe, rapidly progressing loss of vision should seek immediate medical attention, because this may signal elevated pressure in the brain that could lead to permanent blindness, neurologists warn.

What does a decrease in intracranial pressure indicate?

The decreased CPP indicates that there is impaired cerebral blood flow and that autoregulation is impaired. Because the ICP is 24 mm Hg, treatment is required. The patient with a brain tumor is being monitored for increased intracranial pressure (ICP) with a ventriculostomy.

What causes intracranial hypertension to occur suddenly?

Acute intracranial hypertension happens suddenly, usually because of an accident or stroke. Chronic intracranial hypertension develops over time, usually because of a health problem like a blood clot or brain tumor, or from taking certain medicines. If doctors can’t find a reason for the high pressure, it’s called IIH.

What is the relationship between intracranial hypertension and optic nerve damage?

In chronic intracranial hypertension, the increased CSF pressure can cause swelling and damage to the optic nerve—a condition called papilledema. Chronic intracranial hypertension can be caused by many conditions including certain drugs such as tetracycline, a blood clot in the brain, excessive intake of vitamin A, or brain tumor.

What are the treatments for increased ICP?

What are the treatments for increased ICP? The most urgent goal of treatment is to reduce the pressure inside your skull. The next goal is to address any underlying conditions. Effective treatments to reduce pressure include draining the fluid through a shunt via a small hole in the skull or through the spinal cord.
